Answer:
25.6 km/h
Step-by-step explanation:
Omani:
First, 1.5 hours = 1 hour and 30 minutes
and 66 miles = 105.6 km (66 x 1.6 = 105.6)
105.6 / 1.5 = 70.4 km/h
Omani's speed is 70.4 km/h
Adedi:
1 hour and 15 minutes is 1.25 hours
she drives 56 km in 1.25 hours
So 56 / 1.25 = 44.8 km/h
Adedi's speed is 44.8 km/h
Difference:
70.4 - 44.8 = 25.6 km/h
Omani is faster than Adedi with 25.6 km/h
The easiest way to think about this is to give all of the numbers common denominators:
1 can be written as 6/6
0 can be written as 0/6
Now we can see that 5/6 is only 1/6 away from 1, while it is 5/6 away from 0.
So, 5/6 is closer to 1!
